Puppy Toddlers (3 - 6 Weeks) During the Toddler period, puppies emerge on their own from the litter. They venture into the surrounding environment.
This emergence from the litter is a gradual and continual learning experience. During this stage of development puppies learn basic behavioral patterns specific to
dogs. While playing, they practice different body postures, learning what the postures mean and how they affect their mother and litter mates. They learn what it is
like to bite and be bitten, what barking and other vocalizations mean and how to make and use them to establish social relationships with other dogs. Such learning
and activity tempers their own biting and vocalizing. From the age of five weeks, the mother teaches her puppies basic manners. They learn to be submissive to her
leadership and what behaviors are acceptable. If necessary, she growls, snarls, or snaps at them as a form of discipline. When weaning the litter, for instance, the
mother will discipline her puppies so that they will leave her alone. Because the mother disciplines them in a way that they clearly understand, after a few repetitions,
the puppies will respond to a mere glare from her. If a pup has not learned to accept leadership (and discipline) in its early interactions with dogs, its training will be
more difficult. Puppies that are removed from the nest too early tend to be nervous, more prone to barking and biting, and less responsive to discipline. Often they
are aggressive with other dogs. Generally speaking, a puppy taken away from it's mother and litter mates before seven weeks of age, may not realize its full potential
as a dog and companion. To maximize the mental and psychological development of puppies, they must remain in the nest with their mother and litter mates until
seven weeks of age.
